Login problems

Ok so I have not logged in to guild wars for a long time and I decided to come back and see whats changed. Now when i try to log in it says invalid password. On top of this when i try to reset my password it tells me my e-mail is invalid! And yes this IS the right e-mail.

i dunno wut to say
u either forget ur login info
or u got hacked and someone changed it

(if i had to guess i'd say its teh first one)

As Snaek says, you've either forgotten what your account name and /or password are, or you have been hacked.
